2 Litter CO2 Nozzle

When testing out recipes, there's a need to do small batches. Sure I could put a small batch in one of my 5 gallon kegs and carbonate from there, but that almost seems like a waste. And also since I'm new to all of this especially carbonating, I don't know if a 1 gallon recipe in 5 gallon keg may not carbonate as well or at all.

At homebrewing supply shops as well as online, I've come across adapters that fit a quick connect for a CO2 cylinder and a 2 little plastic soda bottle. An adapter like this would certainly allow for making a small recipe. The supply shop that I've been going to sells this commercial product; it's plastic and I'm sure does a great job. I could, however, pay a few dollars more for some used keg parts and have something that will last me forever.

These are the parts that I bought (my supply guy has these parts already available to do this):

A CO2 cylinder adapter, ferret, spacer, two soft washers (for sealing), metal washer (for sturdiness on the plastic 2 litter bottle cap), and a back part that'll screw into the nozzle.

After putting it all together it looks like this:

I had to put it together back and forth a few times trying different orders for the washers but finally got it to seal properly without any leaks.

Cost: $25.

Homemade Root Beer, Soda & Pop

Homemade Root Beer, Soda & Pop by Stephen Cresswell


For anyone making soda pop, I'd suggest buying this book. I'll be using for multiple recipes in the future. I'll note what recipes use this book when I make them. Not only does this book have all sorts of recipes, it talks about ingredients and equipment too. I'll be using this book often.
